Answer:
Hi
Step-by-step explanation:
The first one is 4
The second one is 2.449489743 or 2.45
Starting weight: 5/6 lb. Of this, Jan used 1/5, which would be (1/5)(5/6) lb,
or 1/6 lb, leaving 4/6 lb, or 2/3 lb. unused.
2/3 lb
Now divide 2/3 lb by 8 portions: ----------------- = (2/24) lb/portion, or
8 portions
1/12 lb/portion.
You need to multiply 13.4 by 5,880,000,000,000.
First, we change both numbers into scientific notation.
13.4 = 1.34 * 10^1
5,880,000,000,000 = 5.88 * 10^12
Now we multiply the numbers written in scientific notation.
1.34 * 10^1 * 5.88 * 10^12 =
= 7.8792 * 10^13
The answer is choice A.
In order to solve it you must make each component negative. Multiply them by negative one!
M < 2
Now which numbers would satisfy it? M is less than two... so, m could be one, or any negative number, yeah?
Multiply by negative one. - M and -2 are what you have. If it were one... negative one is less than negative two. Turns out M is less than two.
M < 6
M is less than six. It could be 1, 2, 3, 4, or 5.
-M and -6
Is negative 3 less than -6? All of the numbers are! So, m is actually less than 6
